1. Ke engFTTA?
-FTTA“FiberTo The Antenna” ke moralo o mocha oa marangrang a sejoale-joale a se nang mohala o sebelisang likhoele tsa fiber optic ho hokahanya li-antenna ka kotloloho liteisheneng tsa motheo ho tsoa ho BBU. E nkela sebaka sa coax ea koporo bakeng sa bandwidth e phahameng, latency e tlase (ea bohlokoa bakeng sa 4G/5G). Sebelisa thapo ea fiber optic e nang le boima bo fokolang, ts'ebetso e ntle ea matla (ho pholisa tikoloho), le boleng bo ntlafetseng ba lets'oao, e lumella litora tse nyane haholoanyane tsa sele, tse bobebe le tse nang le bokhoni.
- Hangata ditharollo tsa FTTA di sebedisaThapo ea patch ea CPRI(ho felisoa ha sehokelo sa DLC se lumellanang le lisebelisoa tsa Huawei, Nokia, Ericsson) ho hokela BBU ho RRH, ka hona ho eketsa lebelo la phetiso le ho nolofalletsa sebaka se pharaletseng, se potlakileng le se tsitsitseng sa ho koahela marang-rang a se nang mohala.
- Tharollong ea FTTA, faeba ea optical e matha ho ea toreng ho ea Remote Radio Head (RRH) haufi le Antenna, e sebetsana le matšoao a dijithale; motlakase o fanoa ka mokhanni o arohaneng kapa o kopantsoe ka har'a thapo ea faeba.
2. Melemo ea bohlokoa ea tharollo ea FTTA:
- Mabapi le Bandwidth le Lebelo: E tšehetsa litlhoko tse kholo tsa data tsa 4G/5G.
- Mabapi le Boima le Moroalo oa Moea: Lithapo tse bobebe tsa faeba li fokotsa khatello ea tora le ho hanyetsa moea.
- Mabapi le Bokgoni ba Matla: Li-RRH tse phahameng li sebelisa moea o pholileng oa tlhaho, li boloka matla.
- Mabapi le Botšepehi ba Letšoao: Ho senyeha ha lets'oao le lerata le fokolang ha le bapisoa le koporo.
- Mabapi le ho Kenya: Ho kenya ho bonolo, ho potlakileng ka dithapo tse nyane, tse bobebe.
- Mabapi le ho Tenyetseha: Diyuniti tsa baseband (BBUs) di ka bewa bohareng, e leng se nolofatsang disebediswa tsa tora.
3. Sebopeho sa Marangrang a FTTA
Mehato e latelang ka kakaretso e ameha phetisong ea lets'oao ho tloha yuniti ea sehlopha sa motheo (BBU) ho ea ho Antenna (4G, tora ea 5G):
| Karolo | Mosebetsi | Lihlahisoa tsa bohlokoa |
| Kamore ea Yuniti ea Baseband (Yuniti ea Baseband) | E laola RRU mme e sebetsana le matshwao a baseband | BBUPhanele ea phanele ea faeba optic Cable ea Faeba ea Kantle |
| RRU (phetiso ea Fiber) / BBU-RRU | E fetisetsa matšoao a RRU baseband ka faeba | Thapo ea Patch ea Cable ea Remote Optic ea BSLihokelo tsa FTTA (PDLC, NSN, ODVA, FullAXS, Mini SC, OptiTap, joalo-joalo) Lebokose la Mesebetsi e Mengata la FTTA |
| RRU (Sehlopha sa Radio se hole) | E fetolela lets'oao la optical ho matshwao a RF | Bracket ea ho Hloma ea RRRH |
| RRU – Antenna (Phetiso ea RF) | Antenna e amohela matšoao a RF | Cable ea ho fepa Antenna Feeder Jumper |
| Antenna | Matshwao a se nang mohala: Ho fetisa le ho amohela | Mosireletsi oa ho Tsamaea ha Antenna |
Seteisheneng sa Base sa 4G, fiber (FTTA) e hokahanya BBU le RRU. Likhoele tsa phepelo ea RF li hokahanya antenna.
Ho 5G (moralo wa AAU), BBU, RRU, le antenna di a kopana ho theha DU. RRU le antenna di kopantswe ho AAU ho sebediswa kgokelo ya fiber yohle ho fokotsa tahlehelo ya RF le ho eketsa tshebetso.
4. KCO Fiber e ka u etsetsa eng?
KCO Fiber e tla ba mofani oa hau oa lihlahisoa tsa fiber optic oa FTTA ea tšepahalang. Re ka u fa letoto le felletseng la lihlahisoa tsa fiber optic tse amanang le FTTA tse kang:
- Thapo ea optic ea fiber (Thapo ea optic ea fiber ea kantle, thapo ea ho theola ea ftth, thapo ea optic ea fiber e sirelelitsoeng, thapo ea optic ea fiber ea tšimo, jj)
- Thapo ea patch ea fiber optic ea kantle (Thapo ea patch ea CPRI, Thapo ea patch ea kantle e nang le sehokelo se lumellanang le Fullaxs, NSN, Mini SC, OptiTap, PDLC, ODVA, jj.)
- Lebokose la fiber optic la mesebetsi e mengata bakeng sa kantle
- PLC splitter, thapo ea patch ea kantle ea MPO e nang le likhoele tse ngata, jj.
